The freon has leaked away from the AC on my1986 buick lesabre. I purchased a can of Freon (R134a), but the connectors don't match. Does the 1986 Buick even us this type of freon, and if so what kind of connector do I need. I assume I was trying to connect to the low side which was a connector at the top of the refrigerent cannister next to the firewall.
There are two hoses coming out of the firewall side by side .. one is large and one is small ... they both have valve ports but only the large tube (low pressure side) is to be used for adding refrigerant .. if your connector from the R134a can does not fit ..then you probably have the older R12 system .. that has been outlawed now because of ozone layer destruction caused by it ..you cant get that anymore .. you can however convert your system to R134a but it involves washing out the entire system and replacing all rubber parts ..then attaching adapters so the R134a will connect (availible auto parts) .. by law any remaining R12 in your system has to be recovered, not vented to air .. (actually the r12 is worth a fortune right now but it may not be legal to sell ..its about a 25 times increase) ... the modification process requires a "certified" tech to do the work and the results wont be quite as good as the old r12 ... at least it will work if the system is cleaned out enough .. the two refrigerants dont like each other .. that is, the lubes that are used do nasty things when mixed .. if you wanted to you could become "certified" by attending some classes and passing a test on ozone layer depletion ... now they have discovered that r134a is a powerfull green house gas .. so that also will be phased out in the future .. its like 1600 times worse than CO2 ... r12 was a wonderful chemical .. very hard to beat its performance and stability .. .
